Data Types in Java 7
In this section we will discuss Java 7 Data Types.
Data Types :
Data types are the keywords stored in the reserved memory which we use
to define type of variables.
There are two types of data types defined in java 7 -
- Primitive data types
- Reference data types
Primitive Data Types:
Primitive data types is already defined and represented by the reserved keyword. Value of primitive type don't share state with another primitive values. Java 7 supports eight primitive data types -
- byte
- short
- int
- long
- float
- double
- boolean
- char
Reference data types :
Non-primitive data types are also called reference data types. It is handled by reference. These refer to objects and arrays. it is created by defining constructor of a classes. You can use it to access the objects.
Literals :
When you initialize variable of primitive type, do not use new keyword. we built into the language. Literal is source code representation of a fixed value. It represents directly to your code without requiring computation. literals are used to assign to any primitive type variable.
Example :
short value = 40;
boolean test = true;
